Abstract
Silicon-based ring resonators are indispensable elements in constructing lab-on-chip systems due to their ability to function as label-free photonic sensors. Additionally, employing silicon nitride enables the utilization of low-loss waveguides spanning a broad spectrum of wavelengths, ranging from visible to near-infrared. In this study, we present refractometric sensors utilizing silicon nitride ring resonators operating in the TE mode at approximately 1310 nm wavelengths. Our initial findings illustrate the potential of such a device in biosensing applications, prompting an investigation into its sensitivity regarding the displacement of the resonant peak when transitioning from pure water to ethanol solutions. Subsequent endeavours will focus on exploring functionalization procedures to conduct antigen-antibody binding experiments for more accurate medical applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
